VAPOR-LA1VIR To all whom 'it may concern:

Be it known that I, CHARLES HALSTEAD, a citizen of the United States,residing at Brooklyn, in the county of Kings, State of New York, haveinvented a new and useful Vapor-Lamp, of which the following is aspecification.

My invention consists of a vapor lamp adapte'd for us-e with anincandescentmantle to cause a most brilliant light, and for heatingpurposes.

In order to explain the invention, the accompanying drawing illustratesa satisfactory reduction of the same to practice, but the importantinstrumentalities thereof may be varied, and so it is to be understoodthat the invention is not limited to the specific arrangement andorganization shown and described.

Figure l represents a vertical section of a vapor lamp embodying myinvention. Fig. 2 represents a transverse section of the wick tube. Fig.3 represents a vertical section of a portion of the same, the shutter ofthe lamp being in closed position. Fig. et represents a side elevationof one of the caps employed. Fig. 5 represents a vertical section of aportion of the lamp, the shutter being in operative position. Fig. 6represents a vertical section of a modilication.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings: A. designates the fount of an alcohol orother vapor lamp, and B designates the wick tube thereof, the top C ofwhich is closed and from which rises the vertically arranged rod D, forsupporting the mantle E of suitable order.

F designates a cap whose upper end is reduced, forming a neck F which issupported on the Lipper end of the wick tube and depends therefrom. Inthe side of said cap at or below the neck thereof, are the ports or jetopenings G, and in the base of the cap are the ports or air openings H.Rising from said base is the sleeve J, which encircles the lower portionof the cap F and is separated therefrom, forming the passage K.

llithin the cap F is the collar L, which surrounds and closes the upperportion of the wick tube, it being noticed that a passage lWI existsbetween said collar and cap forming a communication for the ports H andjet openings G, it being noticed that Specification of Letters Patent.

the wick tube is vertically corrugated so as to form ducts N on itsexterior and chiots P on its interior, the walls of the corrugationshaving ports Q therein, the latter providing communications for saidexterior and interior ducts N, P, as most plainly shown in Fig. 2.

lVithin the upper portion of the wick tube is the finely perforated tubeB, which embraces the corresponding portion of the wick B and extendsbelow the base of theports Q, it serving to protect the wick from anexcess of heat in what may be termed the burner head, since the wick isremoved by said tube R from contact with the inner surface of the wicktube.

S designates the shutter of the lamp, the same encircling the wick tubebelow the collar M, it being adapted to be raised and lowered, and whenin closed position to have its upper end S which is of the form of agutter to abut against the lower end of said collar, as most plainlyshown in Fig. 3, it being noticed that said shutter and the adjacentportion of the wick tube are contained in the cap T, which is adapted tobe screwed or otherwise connected with the fount A, said cap havingmounted therein the wheel U, which is adapted to engage the rack V onthe side of the shutter, whereby the latter may be raised and lowered.In t-he neck or upper portion of said cap T, are ports WV, which asshown in Fig. 1, communicate with the atmosphere and with ports X in theshutter, the latter also having ports Y, which as shown in Fig. 3, arebelow said ports X, and are adapted when the wick tube is raised to beplaced in communication with the ports W, in which case the ports X areclosed by the surrounding wall of the neck of the cap, and so cut-olffrom the atmosphere. On the top of said neck is the gutter Z, which isadapted to be supplied with alcohol or other inflammable fluid forheating the portions of the lamp above the same for primarily vaporizingthe fluid, said portions comprising the burner head of the lamp.

A designates the chimney of the lamp, which is supported by the arms B2,the latter being rested on the fount and engaged by the cap T in anysuitable manner.

The operation is as follows-The fount is supplied with alcohol or othersuitable fluid and the wick B is accordingly saturated with the saine,the vapor whereof passes through the perforated tube R and ports Q, theshutter S being lowered and the burner head being primarily heated by asmall quantity ot' fluid placed in the gutter Z and ignited. The vapornow burns below the bottom of the cap F and the shutter is raised sothat its upper end S enters the base of the cap F, so as to close thebottom of the passage M, as shown in Fig. G, when the vapor from withinthe wick tube is directed through the ports Q into said passages, andfrom the latter into and through the jet openings G, where it iningleswith air admitted to the passage K by the uncovered ports H, theresultant vapoi' then burning in the mantle E. Meanwhile, air iowsthrough the ports lV, in the neck of the cap T, into the ports X of theshutter and through the ducts between the wick tube and the shutter, andmingles with the vapor in the passage M, thus supplying a large volumeof air to the vapor for perfect combustion in the mantle and aconsequent brilliant light.

Vfhen the light. is to be extinguished, the shutter is raised so as toabut against. the collar L, when the supply ot' vapor from the wick tubeceases, see Fig. 3. As the ports X are closed, and the ports Y areopened, any existing vapor in the wick tube and to 'i of the fount willescape to the atmosphere through said ports Y and the ports lV, thuspreventing explosion of the lamp.

Should it be desired to use the lamp for heat instead of light, tl e capF, the sleeve J, tlie mantle E and mantle support D are removed, whenthe cup C is placed over the top of the wick tube, when the lamp isinverted and some of the fluid flows through the passages of the wicktube into said cup, when on again turning the lamp to normal condition,the fluid leaves the cup and enters the gutter Z, where as a primer, itmay be ignited and so heat the top of the wick tube, to cause effectivevaporization of the fluid in the latter, the resultant vapor escapingthrough the ports Q, where it may be burned.

Having thus described my invention, what I claim as new and desiie tosecure b v Letters Patent, is l l.
